I recently got a form rejection from an agent's assistant complete with the whole shebang about somebody else will surely see my bright talent, but "alas" not anybody at this agency. About a week later, I received a letter from the actual agent apologizing for the form letter, telling me he liked my work, and asking if he could see something else.
But guess what? It was too late. I'd already signed with somebody else.
(Wow; they sound highly organized.) For you, it must have been one happy week!
